Dr John Armstrong, GP

John is the longest serving GP in Rotorua. He is a highly qualified (John has Fellowship of the Royal NZ College of General Practitioners, the highest qualification available to GP’s) and experienced General Practitioner with a passion for patient care – he has many third-generation patients whom he has known since birth (he even delivered some of their mothers!).

John is committed to making a difference in the area of Maori health. In 2004 he created a unique programme for the Rotorua General Practice Group, called Whanau Ora. (In no way associated with the National/Maori Party coalition initiative that goes by the same name.) John's programme supported individuals with high risk chronic disease by enlisting at least two family members or friends to help engage that individual to overcome associated risks. In so doing, those family members or friends not only became actively involved in contributing to that person, but in so doing, also contributed to their wider family and to their own physical, mental and spiritual well-being. Hence the term: “Whanau Ora”.

He also developed, along with the Rotorua Coroner, a post-mortem diversion scheme, designed to avoid unnecessary post-mortems, particularly because he became acutely aware of local Maori concerns about what was seen as a practise that was largely unnecessary and offensive culturally.

The scheme was introduced by John and the Rotorua Coroner in Rotorua in 1999 and as a result, the number of post-mortem examinations at Rotorua Hospital immediately fell by 50%, and remained that way until new legislation was enacted into New Zealand law in the form of the new Coroners Act 2006, which addressed many of the concerns expressed by Maori. John’s submissions to Parliament were influential in making changes to The Act in 2006.

John continues to advocate on behalf of Te Arawa, and Maori in general, on this subject.

When he’s not working, John loves fishing with his two sons and son-in-law, along with his willing mokopuna.
